250 kVA Power Transformer Price in India: Features, Applications, and Buying Guide

A 250 kVA power transformer is a critical component in industrial and commercial power systems. It ensures reliable voltage regulation, efficient power distribution, and protection of electrical equipment from fluctuations and surges. These transformers are designed to handle medium-load applications, making them ideal for factories, commercial complexes, hospitals, and educational institutions. Understanding the features, applications, and pricing of 250 kVA transformers helps businesses make informed purchasing decisions.

Specifications and Features of 250 kVA Transformers

A 250 kVA power transformer typically operates as a three-phase unit, stepping down high-voltage electricity from 11 kV–33 kV to low-voltage levels such as 415V or 400V. They are available in both oil-immersed and dry-type variants. Oil-immersed transformers are preferred for outdoor installations due to superior cooling, durability, and longer lifespan, whereas dry-type transformers are safer for indoor use because they reduce fire hazards and require less maintenance.

The transformer’s windings are made from high-quality copper or aluminum, with copper offering higher efficiency and conductivity. Advanced insulation materials and robust cores enhance efficiency, reduce energy losses, and ensure long-term reliability. Modern 250 kVA transformer often feature thermal protection, overload safeguards, and compliance with standards such as IS 1180 and IEC 60076, ensuring safe and efficient operation.

Applications of 250 kVA Transformers

The 250 kVA transformer is widely used in industries and commercial sectors that require stable and reliable electricity. Industrial plants rely on these transformers to power machinery and equipment efficiently. Commercial complexes and educational institutions use them for lighting, HVAC systems, laboratories, and administrative areas. Hospitals depend on 250 kVA transformers to maintain uninterrupted power supply for critical medical equipment, ensuring patient safety. They are also employed in renewable energy projects, such as solar and wind power plants, for safe voltage conversion and grid integration.

Price of 250 kVA Power Transformers in India

The price of a 250 kVA power transformer in India typically ranges between ₹2.5 lakh and ₹4.5 lakh, depending on factors such as the type of cooling system, winding material, manufacturer, and customization options. Copper-wound transformers are slightly more expensive due to higher conductivity and efficiency, while aluminum-wound units are cost-effective. Buyers should consider both initial investment and long-term energy savings, along with the quality and reputation of the manufacturer, to ensure optimal value.
